Printed ring slot antenna for circular polarization - IEEE

Designs of circularly polarized printed shorted annual and square ring‐slot antennas are proposed. Circular polarization (CP) radiation of the shorted ring‐slot antennas is achieved by selecting a proper length of the shorted section in the ring slot, which is about 3.9 and 8% of the mean circumference of annular and square ring slots, respectively, and feeding the ring slot using a ... Circularly polarized co-designed filtering annular slot ...

Design of Compact Annular Ring MicroStrip Antenna for ...

In this paper, a compact circularly polarized co-designed filtering annular slot antenna (ASA) is proposed. The antenna comprises a distributed capacitor-loaded annular slot radiator to produce circular polarization (CP) radiation, which is seamlessly integrated with a microstripline bandpass filter (BPF) to enhance out-of-CP-band suppression. Compact SIW Annular Ring Slot Antenna With Multiband ... Abstract: A substrate-integrated waveguide (SIW) cavity-backed annular ring slot antenna with multiband multimode characteristics is proposed in this communication. The antenna consists of an SIW cavity and an annular slot on top surface as the radiator. Two patch-like radiation patterns and one monopolar radiation pattern at three different frequencies are excited by the single fed antenna. An annular-ring slot antenna with CP radiation and ... Abstract: A microstrip-line fed annular-ring slot antenna with circularly polarized (CP) radiation is initially studied. To achieve harmonic suppression for this antenna, the technique of loading a defected ground structure into the ring slot is proposed. antenna | Techn. Activities 2016
